. HEDDLE FRAME.

Application filed` November 18, 1927. Serial No. 234,058.

My invention relates to heddle frames for loolns, and it relates more particularly to improved means, in a heddle frame of the usual type, for supporting the lieddle bars intermediate their ends.

The principal object of my present invention is to provide in a heddle frame improved means for supporting the'heddle bars intermediate their ends, which will securely support said bars against undesirable motion and displacement, but which, however,

will permit the bars to be quickly and conveniently mounted in and dismountcd from the frame when desired.

My present invention contemplates an im* proved form of supporting device in the use of which possibility of the warp controlled by adjacent frames in the loom fouling on the supporting devices will be reduced to a minimum, thereby permitting the greatest possible separation of the warp in the formation of the shed.

My present invention further contemplates a supporting device which may be readily ad justed with respect to the top and bottom rails of the frame, so that the heddle supporting bars will be properly positioned and the heddles will not bind on the supporting bars, or on the other hand be permitted too great an up and down movement thereon.

My present invention further contemplates an improved form of support-ing device which may be inexpensively constructed, and in whichF there will be little likelihood of the parts becoming disarranged or damaged in use.

The nature and characteristicfeatnres of my invention will be more readily understood from the following description, taken in connection with' the accompanyingdrawings forming part hereof, in which Figure 1 is an elevational vview of a heddle frame provided with heddle bar supporting devices embodying the main features of my present invention;

Fig. 2 is a fragmentary detail thereof, enlarged;

Fig. 3 is a sectional view taken approximately on the line 3 3 of Fig. 2, the parts being shown in the normal positions assumed while supporting the heddle bar;

Fig. 4 is a similar view, but with the parts lin the open position for the purpose of removing the heddle bars therefrom or mounting the same thereon; and

Fig. 5 is a perspective view of the supporting devlce detached from the rail of the heddle frame.

Referring to the drawings, the licddle frame there shown comprisesl top and bottom rails 10, connected at their ends by means of side strips 11. Extending fromcnd to end of the heddle frame and arranged near the top and bottom rails 10, in the usual manner, are the heddlc supporting bars 12, on which the heddles 13 are mounted, also in the usual manner.

The devices comprising the novel portion of the present invention are located at suitable locations on the inner edges of the top and bottom rails 10. Each of these devices as shown in the drawings includes a bolt member 20, having a shank 21, the end of which is threaded as at 22 in the manner similar to an ordinary wood screw, with the exception that the same is not tapered for the greater portion of its length.

The bolt member 2O is also provided with ahead portion 23, preferably made by flattening and spreading the material of the rod from which the bolt member is formed. In the head portionof the bolt member there is provided a recess 24, in which the heddle bar l2 is adapted to be seated.

At the end of the recess 24, toward the free end of the head portion, there is provided a lip 25 which assists in properly positioning the heddle bar 12 within the recess 24, and also servesto engage and retain the marginal edge of the heddle bar when the same is locked within said recess 24 in the manner to be hereinafter explained.

Mounted on the head portion of the bolt member 2O is a slide member 30. The slide member 30 is provided at one end vwith a lougitudinal slotg31. The other end of the slide member 30' is bent over as at 33, andthe bent over portion 33 is provided with an aperture 34, through which `the shank portion 21 of the bolt member 20 extends. In this manner, one end of the slide member 30 is properly positioned with respect to the head portion 23 of the bolt v2O. The other end of the slide member 30, which is provided with the slot 31, is positioned with 'respect to the ,head portion 23 of the bolt 20 by means of a rivet 36, which extends through a portion of the slot 31. The rivet 36 is secured in the head port-ion 23 of the bolt member betweenl the recess 24 and the shank portion 21.

The portion of the Slide member adjacent the bent over portion 33 thereof, is disposed out of the main plane of theslide member, as at 35, to clear the shank portion of the bolt 20 and also to aiiord'a larger seat upon the bent over portion 33 of the slide member.

A coil spring surrounds the smooth or unthreaded portion of the shank 21 of the bolt 20. Said coil spring bears at one end against the bent over portion 33 of the slide member 30, and at its other end is seated in a recess 41 provided in the inner edge of the rail 10 of the heddle frame proper. If desired, a washer 42 may be interposed between the end of the coil spring 40 and the bent over portion 33 of the slide member 30.

The spring 40 normally tends to cause the slide member 30 to occupy aposition as shown in Fig. 3 of the drawings, whereby the heddle bar 12 will be engaged by the slot 31 of the slide member 30, and normally will be retained thereb Vin position within the recess 24 of the head portion 23 of the bolt 20. It will here be noted that the heddle bar will be engaged at one marginal portion by the slotted slide member 30, and at the other marginal portion will be retained against coming out of the recess 24 by the lip 25 provided at the other end of said recess.

The movement of the slide member under the tension of the spring 40 is limited bythe engagement of the inner end of the slot' 31 with the rivet 36, the head of which rivet, as hereinbefore pointed out, serves lto guide the slotted end of the slide member 30 with respect to the recessedhead portion 23 of the bolt 20.

The operation of vthe device may now be readily understood. The supporting devices being mounted in the heddle frames at desired locations upon the inner edges of the top and bottom rails 10 thereof, andthe heddle bars with the heddles mounted thereonu being placed in the frame in the usual manner, with the ends thereof secured in position in theside strips 11 of the frame by fastening devices of any preferred type, the slide member 30 is then manually pushed to the open position as shown in Fig. 4 of the drawings, the projecting part of the bent oyer portion 33 affording a' convenient finger piece for the manipulation of the slide member.

The heddle bar 12 is now inserted in the recess 24 provided in the head portion 23 of the bolt 20, and when properly positioned therein, the slide member 30 is released and permitted to return to the normal locking position as shown in Fig. 3 of the drawings, being thereafter maintained in such position by the coil spring 40.

The slot 31 of .the slide member 30 will now serve to retain the heddle bar 12 within the recess 24 of the head portion 23 of the bolt 20, and will securely hold the sameA whereby the same will bind upon the heddle supporting bars, or on the other hand, should it be found that the heddle bars are so positioned that the heddles are permitted too y much up and down movement in the frame,

the proper adjustment of the device for supportingl the heddle bars maybey easily made by rst removing the heddle bar from the 'supporting device, and then threading the bolt in orout with respect to the rail 10 in which'it is mounted until the recess 24 of the head portion 23 of the bolt member 2O is properl? located.

will be seen that with devices constructed I as hereinbefore described2 the heddle bars will be fiXedly supported lntermediate their ends, whereby undue lateral movement of the same will be effectively prevented, (and that adjustment of the supporting device with respect to the top and bottom rails may be quickly and conveniently made, so that the heddle bars may at all times be properly positioned. It .wille also be apparent that the adjustment of the supporting devices when made will be maintained by reason bf the boltl I claim as new and desire to secure by Letters Patent, is:
